Western flock is really moving! Most
of the flock has left Texas, and another sighting
in Canada occurred. An
unusually large group of 18 Whoopers is flying together, and someone
proved it with photos and video. In sadder
news, the flock of 237 became 236 when a male with a long and fascinating
life was found dead in North Dakota; his story will make
you feel good. (He was the 29th confirmed whooper sighting in North
Dakota this spring!)
Meanwhile, by April 16 an estimated 50 Whooping Cranes had
the Wisconsin Finish
pairs are creating excitement by nesting. First Family parents
#211 and #217, pair #213 and
#218, and pair #209 and #416 are sitting on eggs. Will more
new nests soon appear? Will other chicks
join the flock's first crane-kid, now almost a year old?
In the Eastern flock #509, #516, #615, #523, and DAR 27_06 are still
in Florida. Wayward female
New York state. Crane #318 and DAR 33-05 are in two Michigan locations,
and DAR 28-06 is in
Indiana. Two cranes (#524 and #202) are unaccounted for, and one
more (DAR 26-06) has died. How do we know this? Read on!
Tracking with Radio Telemetry
Thanks to the terrific WCEP Tracking
Team, we know where most of the new flock's cranes are. Every
whooping Crane in the
flock wears a leg
band with a radio transmitter. How do they work? Tracker Lara shares the answer.

Big Week |Read Tom's report >>
in the much bigger Western flock don't wear any transmitters. Only
a very few of the oldest cranes wear bands. Yesterday, one of those cranes
was found dead in North Dakota. This "senior
citizen" had a colorful past
that helped us learn a lot about Whooping Cranes, and
Tom tells us how in his report.
Tom flew over the refuge yesterday and he brought us the latest count. Find
out why it
was a BIG week for crane migration in the Central Flyway!

Who's Laying Eggs?
and sightings tell us that cranes
#105 (male) and #519 (female) arrived on #105's old territory at Necedah
NWR on April 16.
- (A) Do you think there's hope of this pair having a chick this spring?
why or why not. Hint: Think about the age of these cranes
(clues are in their numbers), and the age at which cranes breed.
for Bonus) Experts are a little puzzled that there are
so few nests when so many of the flock
have reached breeding age. What do you think might explain this?

are laid by birds living at Patuxent. Other eggs are shipped there from
from the San Antonio Zoo were shipped in this travel case to
Patuxent Wildlife Research Center in Laurel, Maryland April 13th.
crane-rearing buildings at Patuxent Wildlife Research Center are off-limits
to the public. The new ultralight-led chicks are hatched here.
Migration requested 20 to 24 chicks for its
next ultralight-led flock. Soon we'll meet the first chicks of
of 2007. Stay tuned!
